The engines with 2.5 L (2,490 cc) displacement, identified as the Volvo Penta AQ151 (8 valve) and AQ171 (dohc 16 valve) models, got a forged crankshaft with a longer stroke of 86 mm (3.39 in) together with pistons with a 3 mm (0.12 in) lower compression height. The 2.5 L (2,490 cc) blocks still had B230 cast in the block.

The 171-cubic-inch (2.80 L) engine was the first and most common member of this family. It featured splash lubrication.For its last year (1928) it gained a revised carburetor, higher compression, aluminum pistons, and larger valves for a rating of 35 horsepower (26 kW) at 2,200 rpm.
In some older engines (such as the Chevrolet Gen-2 "Stovebolt" inline-six, the GMC straight-6 engine, the Buick Straight-eight, and the Chrysler "Slant 6") the bore pitch is additionally extended to allow more material between the main bearing webs in the block. For example, in an L6 the first pair (#1 & 2), center pair (#3 & 4), and rear pair ...

2 O 4 as oxidizer. It was developed in the early 1970s by TRW as a derivative of the lunar module descent engine (LMDE). This engine used a pintle injector first invented by Gerard W. Elverum Jr. [1] [2] [3] and developed by TRW in the late 1950s and received US Patent in 1972. [4] This injector technology and design is also used on SpaceX ...
